How to Use a Registration Key on a Memory StickI was asking what I do with a registration key on a memory stick. I unregistered one of my copies and then used the option "USB (Portable) Key" on the registration screen to create a file on a memory stick. Now what do I do to use that key? I could not find any documentation.
Issue With Checking Registration StatusAlso, I tried using the "Show License Info" option on the registration screen. I have entered my registration key, but that option remains greyed out. Oh, I just read the documentation more carefully and went to the Register option under the Help menu instead of the Option menu. There it works! This strikes me as a bit of a bug. Getting to the registration dialog in two different ways should not give different results. Or the "Show License Info" button should not appear on the screen reached from the Options menu.
